The General Services Administration released two studies September 26 finding that workplace-specific lighting and advanced power strips could provide between 26 and 63 percent energy savings in buildings compared to normal lighting. The studies, tested under the Green Proving Ground initiative in cooperation with the Department of Energy’s National Laboratories, found that lighting technologies include dimming equipment, occupancy sensors, and lighting management systems, and energy savings depend on how workspaces are used. Lighting accounts for 39 percent of electricity costs in office buildings. Advanced power strips could provide between 26 and 50 percent energy savings.
